In the field of smart healthcare, video consultation has become a key way to provide medical services for remote patients. In this process, it is essential to ensure the legal identity of both parties to the communication and to protect patient privacy data from unlawful interception and tampering. Therefore, a controlled quantum authentication confidential communication protocol is proposed by using the entanglement exchange ability and measurement correlation of Bell states. With the assistance of a trusted third party, the protocol first achieves the mutual authentication of the communication parties, so as to prevent malicious users from communicating by pretending to be medical specialists or patients. The trusted party then further assists the communicating parties in generating two implicit shared keys, which they use to encrypt the message and its digest, ensuring that the patient's sensitive data is not intercepted or tampered with. In addition, the quantum sequences are transmitted only once in the channel, reducing the loss and noise effects caused by multiple transmissions. Security analysis shows that the protocol can effectively resist participant attacks and outside attacks. In addition, performance analysis provides computation in terms of qubit efficiency and experimental simulation results of the protocol.

With the digitization and networking of medical and health data, intelligent medical devices are widely used to monitor patient health status and provide personalized medical services. However, these devices involve a large amount of personal health data and must ensure data security. The data security and privacy protection in the new complex network environment has become one of the important challenges in the field of healthcare. This study aims to propose a post quantum attribute based authentication key agreement protocol applicable to intelligent healthcare, to address the security risks and risks of medical data communication under traditional cryptographic systems. This new protocol is based on attribute authentication encryption technology without certificates on the grid, which completes mutual authentication and establishes secure communication through attribute and access control policies, and can optimize the deployment of certificate system components in public key infrastructure. Meanwhile, this scheme belongs to the post quantum cryptography protocol and has the ability to resist quantum computing attacks. Based on comprehensive analysis, this scheme can achieve certain advantages in execution efficiency and security, and can provide a more reliable choice for secure communication in the field of intelligent healthcare.
Abstract In the Internet of Medical Things (IoMT), sensors automatically collect data and transmit it to hospital servers, where doctors provide professional medical advice. The emergence of IoMT has significantly reduced the burden on chronic-disease patients and improved their life security. However, the transmission of patients’ medical data still faces serious confidentiality and integrity risks. This paper proposes a novel healthcare-system architecture that integrates a controlled-authentication semi-quantum key-negotiation (SQKN) protocol, leveraging the unconditional security of quantum cryptography to mitigate potential data attacks. The hospital server acts as a trusted controller that supervises every protocol run and authenticates all participants, which effectively thwarts man-in-the-middle and identity-spoofing attacks. The semi-quantum design further minimizes the quantum-device burden on patients’ side. Experimental simulation under realistic noise (QBER ≈ 0.03 at 0.02/0.04 noise level, 3 000 shots) shows the protocol keeps the quantum-bit error rate below 3 %, while the overall key-generation efficiency reaches 92 %, demonstrating that the scheme resists known attacks and maintains high quantum efficiency for safeguarding IoMT data security.
In Wise Information Technology of Medicine, to ensure both confidentiality and integrity of the data created during online joint consultations, and to solve the problem that ordinary users cannot afford expensive quantum devices and are vulnerable to man-in-the-middle attacks during communication, this paper proposes a three-party controlled authentication semi-quantum key agreement protocol, leveraging the measurement retransmission operation and the entanglement properties of Cluster states. With the help of a trusted controller with full quantum capabilities, the identities of three semi-quantum parties are authenticated, and a shared key is negotiated fairly for subsequent communication. Since the semi-quantum participants only need to perform simple quantum state preparation, measurement and reflection operations, the protocol reduces the requirements for participants' capabilities and equipment. Moreover, the protocol prevents man-in-the-middle attacks by authenticating the identity of participants. The security evaluation demonstrates that the protocol is capable of effectively defending against both internal participant threats and external intrusions. Moreover, a comparison with existing semi-quantum key agreement protocols reveals that this protocol offers certain advantages when its functionality and performance are comprehensively evaluated.
Authentication is one of the security services that ensures sufficient security of the system by identification and verification. Also, it assures the identity of the communicating party to be that the claimed one. To build a quantum channel between two unauthenticated to each other parties, first, a trusted authority is needed to establish a mutual authentication with each party. Using Bell measurement and entanglement swapping, we present a protocol that mutually authenticates the identity of the sender and the receiver, then constructs a quantum channel based on Bell basis. After, the sender and the receiver use the quantum channel to communicate using entanglement-assisted quantum communication protocols. Additionally, the protocol renews the shared secret key between the trusted authority and each user after each authentication process. The protocol provides the necessary authentication and key distribution to create a quantum channel between the sender and receiver.
Healthcare requires data encryption to safeguard sensitive patient information from unauthorized access or breaches. Encryption ensures that data is encoded into a secure format, making it unreadable to anyone without the decryption key. This helps maintain patient privacy, protects against identity theft, and ensures compliance with data protection regulations like HIPAA (Health Insurance Portability and Accountability Act.). With encryption, healthcare organizations can mitigate the risk of data breaches and uphold trust with patients by ensuring the confidentiality and integrity of their medical records and personal information. Quantum cryptography emerges as a revolutionary solution, offering unparalleled encryption for healthcare data. This process initiates with the meticulous crafting of quantum states to encapsulate healthcare data securely, ensuring precise encoding. Subsequently, quantum entanglement is established between sender and receiver, creating a secure communication channel resistant to interception attempts. Quantum key distribution then generates a secure key leveraging entangled quantum states, becoming the cornerstone of encryption. Quantum encryption shields healthcare data in an impenetrable veil of secrecy, leveraging the complexities of quantum mechanics to thwart unauthorized decryption attempts. The decryption process, facilitated by the shared secure key, unveils the encrypted healthcare data exclusively to authorized parties, preserving confidentiality with unparalleled precision. The result reveals quantum cryptography's superiority in healthcare data encryption. At 150-bit key length, quantum cryptography takes 352,237 milliseconds vs. AES's 310,285 milliseconds. For a 14 KB input, quantum cryptography requires 7 milliseconds compared to AES's 12 milliseconds. These metrics highlight quantum cryptography's efficiency gains and transformative potential in healthcare data security, promising both enhanced security and efficiency benefits.
